Area Forecast Discussion . UPDATED National Weather Service Austin/San Antonio TX 1208 PM CST Thu Jan 23 2020
UPDATE. Please see the 18Z aviation forecast discussion below.
AVIATION. VFR conditions are expected at area TAF sites through the current forecast period. Northwest to northerly winds will continue through this afternoon and may become gusty for a brief period early this afternoon along I-35. Winds will then decrease around 00Z. Light north-northeast winds remain along I-35 overnight, with winds transitioning to a more easterly direction at DRT.
PREV DISCUSSION. /ISSUED 246 AM CST Thu Jan 23 2020/
SHORT TERM (Today through Friday) . Surface analysis early this morning shows a surface low over North Texas with an attendant cold front extending along a Mineral Wells to San Angelo to Dryden line. The departure of a shortwave trough from North Texas will pull the surface low and cold front towards the southeast through the remainder of the morning hours, resulting in the cold front reaching the Hill Country before dawn and Interstate 35 corridor closer to 8-9 AM. Before frontal passage, dense fog will linger from the Edwards Plateau into the Hill Country and in most of the region east of Interstate 35 as moisture from yesterday's rain remains trapped beneath a shallow inversion located about 1800 ft AGL on aircraft soundings out of San Antonio. Northwest winds increasing to 10-15 MPH behind frontal passage combined with mixing from insolation will allow for fog and low stratus to lift around or shortly after frontal passage for most of the region.
GOES Total Precipitable Water satellite imagery this morning shows column moisture under one inch across the region and no rain is expected with frontal passage. Despite the cold front, dry air and downsloping winds behind the front will allow for temperatures to warm into the mid 60s to mid 70s for much of the region today. Cloud cover trends will need to be monitored through the morning in Central Texas for potential temperature adjustments as this area looks to see low stratus linger the longest this morning.
Clear skies tonight and light winds as a surface high slides across South Central Texas behind the front will promote excellent radiational cooling conditions, leaving lows in the mid 30s to mid 40s by sunrise. A light freeze may be possible in low-lying areas of the Hill Country. Dry and pleasant weather continues on Friday with high temperatures climbing into the 60s to low 70s.
LONG TERM (Friday Night through Wednesday) . With Southeasterly winds returning Friday, moisture returns to the area keeping low temperatures for Friday night mild and cool. Saturday will be fair with highs in the mid to upper 60s. Continued increasing moisture and clouds keep lows for Saturday night in the 50s for most of the area. By Sunday a weak cold front is dragged across the area bringing chances for rain for areas along and east of I-35 and with little to no change in temperatures as highs remain in the low 70's. The brief wind shift from the weak front will interrupt the moisture return before winds shift back to southeasterly by Monday afternoon. The next approaching trough and associated front progged for Tuesday. With continued disagreement among models for the timing and how far the trough digs south, a blend of solutions was used as both will factor in for rain chances for Tuesday and Wednesday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
